“…Deeper penetration of asperities was attributed due to the high value of friction in the early cycle under high load. With increasing load, braking energy is enhanced as well, resulting in an early rise in temperature, 25 which changes the thermal and mechanical properties of polymer composites. As a result, the matrix was plasticized early on, resulting in adhesion to the counter surface as well as delamination from the composite's surface.…”

The present work primarily focuses on the thermo-mechanical and physical properties of polymer composites. The effects of normal load, sliding frequency, and temperature on the reciprocating sliding performance of Carbon fiber (CF) segments are evaluated. These CF segments are coated with graphene nanoplatelets (GNPs), and carbon fiber-reinforced polymer (epoxy) composites (CFRPs). Experiments are carried out at three different normal loads (55 N, 75 N, and 95 N), sliding frequency (8 Hz, 12 Hz, and 16 Hz), and temperature (25°C, 40°C, and 60°C). The experiments are conducted for 20 min with a constant stroke length of 1.5 mm against a 62 HRC hardened chrome steel ball as a counter surface material. Optical microscopy and Scanning electron microscope (SEM) have been used to examine the worn surfaces. In addition, an artificial neural network (ANN) is applied to model the coefficient of friction on the basis of different parameters. It has been observed that adding GNPs to carbon fiber strands improves the strand’s bonding tendency with the matrix, resulting in an increase in wear resistance. With the addition of GNPs on carbon fiber strands, the specific wear rate decreased by 32.39%, respectively, while the thermal conductivity increased by 47.95%. The coefficient of friction increases with the normal load up to 75 N and then drops. This is due to fiber fragments and friction film at high loads. As the sliding frequency and temperature increase, the friction coefficient gets reduced. It has been found that the ANN model is able to predict the coefficient of friction with high accuracy.

“…In recent years, the polyether skeleton with its low viscosity and good solubility has been widely used in materials. Since the ether bond has low cohesive energy and is easy to rotate, the material prepared by it has excellent mechanical properties [13]. Some researchers use polyether to modify materials, such as Yang H. et al, who synthesized two new polyethers and used them as toughening agents to physically modify the phenolic foam, finding that the total heat release rate of the modified foam can be reduced by up to 42% [14].…”

In the present study, acetoacetic ester-terminated polyether was selected as a modifier to prepare a new type of polyether phenolic resin, which was successfully prepared by pre-synthesis modification. It is used to prepare interpenetrating cross-linked network structure modified phenolic foam with excellent mechanical properties. Fourier transform infrared spectroscopy (FT-IR) and nuclear magnetic resonance (1H NMR, 13C NMR) were used to characterize the molecular structure of the polyether phenolic resin. The results showed that the acetoacetic ester-terminated polyether successfully modified the phenolic resin and introduced a polyether skeleton into the resin structure. The effect of changing the added amount of acetoacetic ester-terminated polyether from 10% to 20% of the phenol content on the mechanical properties and microstructure of the modified phenolic foam was investigated. The results showed that when the amount of acetoacetic ester-terminated polyether was 16% the amount of phenol, this resulted in the best toughness of the modified foam, which had a bending deflection that could be increased to more than three times that of the base phenolic foam. The modified phenolic foam cell diameter was reduced by 36.3%, and the distribution was more uniform, which formed a denser network structure than that of the base phenolic foam. The bending strength was increased by 0.85 MPa, and the pulverization rate was as low as 1.3%.

To modify the tribological properties of epoxy (EP), additive phases, such as inorganic/organic lubricating fillers, are often introduced to form EP‐based solid‐lubricating composites, which are extensively utilized in industrial sectors like aerospace, automotive, and electronics. The composite methods can be divided into single‐phase composite and multiphase composite. Single‐phase fillers can improve the tribological properties of the composite while the content and distribution of the fillers should be precise controlled. Multiphase fillers offer significant advantages in enhancing the comprehensive properties of EP, making them more suitable for practical harsh environments. This review investigates the progress in research on the tribological properties of EP‐based solid‐lubricating composites and provides an outlook on the future development of lubricating fillers.Highlights In this paper, the commonly used lubricating fillers in EP‐based solid‐lubricating composites and their composite methods, including inorganic and organic fillers, were reviewed. The various EP‐based solid‐lubricating composites, and their lubrication or wear mechanisms were introduced in detail, and the future development directions of the composites were prospected.
